English Abstract

The invention provides cardboard-based structures comprising two or more, generally elongated elements angled with respect to one another and being cut out of a multi- layered cardboard-based piece that comprises at least two layers of a single cardboard sheet folded about a longitudinal reinforcing member. The invention further provides frames, preferably human-powered vehicle frames, constructed from structures of the invention, as well as methods for producing structures of the invention.


French Abstract

L'invention concerne des structures à base de carton comprenant deux éléments ou plus, généralement allongés, coudés l'un par rapport à l'autre et découpés dans une pièce à base de carton à plusieurs couches, qui comprend au moins deux couches d'une feuille unique de carton pliée autour d'un élément de renfort longitudinal. L'invention concerne en outre des châssis, de préférence des châssis de véhicule à propulsion humaine, réalisés à partir des structures selon l'invention, ainsi que des procédés de production de structures selon l'invention.

CLAIMS:
1. A frame part comprising
two or more, generally elongated elements angled with respect to one another
and
being cut out of a planar multi-layered cardboard-based piece that comprises
at least two
layers of a single cardboard sheet folded about a longitudinal reinforcing
member, to
thereby define a longitudinal fold region comprising said member embraced by
portions
of the cardboard sheet, such that at least two of said elongated elements
being integral
with one another and are cut as a single integral structure out of said planar
multi-layered
cardboard-based piece; and
at least a first element of said elongated elements comprises at least a
portion of
the fold region, said at least a portion of the fold region extends the length
of said first of
said elongated elements.
2. The frame part of claim 1, wherein said reinforcing member has a rounded

cross-section.
3. The frame part of claim 1 or 2, wherein said reinforcing member is made
of
cardboard or wood.
4. The frame part of any one of claims 1 to 3, wherein said first element
comprises
substantially the entire fold region.
5. The frame part of claim 4, wherein said reinforcing member extends the
length of
said first element.
6. The frame part of any one of claims 1 to 5, further comprising a support
element
extending between said first element and at least one other of the elongated
elements.
7. The frame part of claim 6, wherein the support element is made of
cardboard.
8. The frame part according to any one of claims 1 to 7, wherein one or
more of said
elongated elements has free ends connectable to other structures or other
structural
elements.
9. The frame part of any one of claims 1 to 8, wherein at least the first
element has a
load-bearing or bend-resistance property that is larger than a load-bearing or
bend-
resistance property of the longitudinal reinforcing member.

- 10 -
10. The frame part of any one of claims 1 to 9 being capable of supporting
a load in a
direction perpendicular to said first element, which is at least 10 times the
weight of said
frame part.
11. The frame part of any one of claims 1 to 10, comprising an external
coating.
12. The frame part of claim 11, wherein the external coating comprises at
least one of
a fire-resistant coating, a liquid-resistant coating, and a scratch-resistant
coating.
13. The frame part of any one of claims 1 to 12, being a component of a
frame of a
human-powered vehicle.
14. The frame part of claim 12, wherein at least one end of at least one of
the
elongated elements is configured for articulation to a pedal crank.
15. A human-powered vehicle, comprising two or more frame parts, each of
the parts
being according to anyone of claims 1 to 14.
16. The human-powered vehicle of claim 15, sized and shaped for a human
rider.
17. A method for manufacturing a frame part, comprising:
forming a generally planar two-layer cardboard-based piece with a longitudinal

fold region at its edge, said forming comprises folding a single cardboard
sheet about a
longitudinal reinforcing member; and
cutting out a structure from the planar piece, the structure comprising at
least two
elongated elements, a first of the at least two elongated elements extends
along said fold
region and is integral with at least one other of said elements and angled
thereto, such
that the at least two elongated elements are cut from the planar piece as a
single integral
structure.
